The platform

Who owns which data, which model version made which decision, and how any number can be audited.

Runs through every layer: zoning, identity, encryption, and the assumption that the site may be air-gapped.

The dashboards, the field app, the alerts and the operations centre — where people actually meet the platform.

The petroleum engineering logic — nodal analysis, allocation, reliability, integrity — as services anything can call.

Where the physics models and the machine-learning models actually run, and where they are checked.

Where everything is stored, cleaned, named consistently and made traceable.

The one-way road that brings control-system data out safely, and never lets anything back in.

The sensors, cameras and small computers that sit at the wellhead and in the plant.
